Application December 15, 1931, Serial No. 581,135 3. Claims. 01. 220-42) This invention relates to cans and has for its object to provide a novel can which comprises a body portion and a neck portion separate from the body portion but permanently secured thereto, which neck portion is shaped to provide a tight joint for the cover, and also to furnish a suitable locking means for retaining the cover in place.

. Another object is to provide a can of this type which will be free from any interior shoulder that will interfere with or prevent the contents of the can from being freely and completely poured out.

Other objects of the invention are to improve generally cans in various particulars hereinafter set forth.

In the drawing wherein I have illustrated some embodiments of my invention, Fig. 1 is a fragmentary sectional view through a can embodying *my invention showing the cover closing the can;

Figs. 2, 3, 4 and 6 are fragmentary sectional views showing a different embodiment of the invention;

Fig. 5 is a top plan view of the can with the cover removed.

Referring first to the construction shown in Fig. 1, 1 indicates the body portion of the can and 2 the neck portion. The body portion 1 is formed at its upper end with a seat 3 on which the neck portion rests, said seat being provided for by bending the upper edge of the body porbody laterally in an outward direction as will be presently described.

The neck portion 2 is preferably formed separately from the body portion 1 and in the construction shown in Fig. 1 said neck portion is provided with an outwardly-directed flange 5 which rests on the seat 3 and is soldered or otherwise permanently secured thereto. Said neck portion 2 is also formed with the upstanding cy- 'lindrical wall 4, which rises from the upper edge of the body portion and which in Fig. 1 has a diameter less than that of the can body, and with the interior cylindrical wall 7 which is spaced from the wall 4 and is connected thereto by the rounded portion 8 forming the top edge of the can, said cylindrical wall '7 providing a wall with which the cover has frictional engagement.

The neck portion 2 also has the interior skirt 9 which extends downwardly and outwardly from the lower edge of the cylindrical wall 7 into engagement with the side wall of the can body at 9. The flange 5 is also illustrated as having a depending exterior. skirt portion 6 which fits around the outer wall of the can body 1 and is secured thereto. I

The can is closed by a suitable cover 10 and this is provided with the upstanding cylindrical portion 12 which frictionally fits the cylindrical wall '7 of the neck to make a tight joint. The cover is also provided with the curved portion 42 which fits around the top edge 8 of the can and with the rim portion v11 which embraces the wall 4.

For locking the cover to the can the wall 4 is provided with a plurality of projections 39 produced by deforming the rim portion 11 at proper points. These deformed or projecting portions 39 are shaped to present downwardly-facing shoulders 40 and the edge of the rim portion 11 of the cover is bent inwardly 'as shown at 43 to interlock with the shoulders 40.

The upper faces of the projections 39 are rounded so that when the cover is applied to the can the inturned edge 43 of the rim 11 of the coverwill wipe past the projections 39 and snap over the shoulders 40 thereby locking the cover to the can body. The cover can be removed by prying the lower edge 43 of the cover out of engagement with the shoulder 40 by means of a suitable implement which may be fulcrumed on the shoulder formed by the flange 5 of the neck member. It will be understood that a suitable ring or gasket of packing material will be used between the surfaces 8 and 42 in order to make a tight seal. v p

In Fig. 2 I have illustrated a different embodiment of the invention-in which the body por tion of the can is continued upwardly from the seat and is bent to form a bead that is enclosed between'the exterior and interior walls of the 5 neck portion. In this embodiment the body portion of the can is indicated at 13 .and said body is deformed to form the seat portion 14 to which the neck section 15 is secured.

The body is also provided with the upstanding portion 16 above the seat portion and the upper end of this portion 16 is bent to form the usual bead 17.

The neck portion 15 is formedwith the'exterior cylindrical wall 18 which closely fits the wall 16 and with the outwardly-directed flange portion 19 which rests on and is secured to the seat portion 14. Said neck is also formed with the depending skirt 20 which embraces the body portion. This neck portion is soldered or otherwise permanent- I ly secured to the body. The neck portion is further provided with the cylindrical inner Wall 21 with which an upstanding cylindrical wall of the cover is adapted to have frictional engagement.

The lower edge of this wall 21 is bent outwardly at an inclination as shown at 22, and engages the inner face of the side wall of the can body.

The can body is shown as provided with an exterior groove 23 which forms an interior rib 24 against'which the lower edge of the outwardlybent portion 22 has engagement. This rib 24 makes a seat for the outwardly-bent edge 22 and thus assists in retaining the neck portion in proper position even though a considerable pressure is applied to the upper edge thereof.

A can of this type is also adaptedi'or use with the same type of cover as that above referred to, that is, a cover which is provided with an upstanding cylindrical wall adapted to frictionally 2o fit within the inner cylindrical wall 21 of the neck portion and which is also provided with a rim portion to embrace the top of the neck portion and to be locked thereto.

In Fig. .41 have shown still a difierent em- 25 bodiment of the invention wherein the upper edge of the can body 25 is bent outwardly as shown at 26 toform a seat for the neck portion. In this embodiment also theneck portion, which is indicated generally at 27, is ,formed'with the exterior .cylindrical wall 28 and with the rim portion 29 spaced from the wall 28 and which fits within the upper end of the can body 25. Said neck portion is also formed with the laterally-extending flange member 30which rests on the seat 26.

...As shown in said figure .the flange 30 and the seat 26 are permanently secured together by means of a double lock seam which is produced by bending the extreme edges 01 the flanges 26 and 30 back on themselves with a double told.

. These two parts, however, might be permanently united in some other way without vdeparting from the invention. Where the double lock seam connection .is used it is desirable to have the space between the wall 28 and the .rim 29 to receive a suitable tool to assistiniorming thejoint. In this embodiment also the neck portion 27 has the inner cylindrical wall 31 with which the cover has frictional contact and the lower end or this wall31 is flared outwardly as at 32 into engagement with the inner wall of the can.

60 wardly to meet the inner wall of the can.

In Fig. 6 I have shown still a difierent embodiment of the invention which is somewhat similar to that shown in Fig. except that the rim portion of the neck section is deformed to provide downwardly-directed shoulders with which a bead on the can cover .co-operates to lock the cover in place.

In the construction shown in Fig. 6 the can bodyis designated 50 and the neck section is indi- 7Q catedat 51. The can body is provided with a seat 52 on which the flange portion 53 of the neck rests and the neck and the body portion are secured together by the double lock seam 54. The neck is made with the rim portion 55 which fits within the can body and with the vertical walls 56, 57 which are spaced from each other, the lower end of the wall 57 being bent outwardly into engagement with the body of the can as shown at 58. In this embodiment of the invention the rim portion 55 is deformed at separated points to provide downwardly-facing shoulders 59.

The can cover 60 is formed with a cylindrical 'Wall 61 adapted to frictionally engage the wall 5'7 of the neck section and it is also provided with the skirt portion 62 which is formed with a bead 63 at its lower edge that is adapted to interlock with the shoulder 59 to lock the can cover to the can body. When the can cover is applied to the body to close the can the bead 63 will wipe by the deformed portions of the rim and snap under the shoulders 59 thereby lockingthe cover to the can.

I claim:

1. A can provided with a body portion having a neck-receiving seat at its upper end, a neck portion resting on and secured to said seat, said neck portion having an exterior cylindrical wall rising above the seat and of less diameter than that of the body portion, and also having an interior cylindrical wall spaced from the exterior wall and further having a skirt extending downwardly and outwardly from the lower edge of the interior Wall into engagement with the wall of the body portion there being an upwardly-facing exterior square shoulder where the body portion joins the neck portion.

2. A can provided with a body portion, a neck.

portion having an exterior cylindrical wall rising above the upper edge of the body portion and of less diameter than that of the body portion, and also having an interior cylindrical wall spaced from the exterior cylindrical wall and of greater vertical dimension than said exterior cylindrical wall, and further having a skirt extending downwardly and outwardly from the lower edge of the interior cylindrical wall into engagement with the wall of the body portion, said body portion having an interior shoulder situated below and engaging the lower outwardly-flared edge of the skir 3. A can having a body portion, the upper part of which is bent inwardly at substantially right angles to the wall of the can body thereby to form a flat neck-receiving seat, the material at the inner edge of said seat being bent downwardly, a neck portion resting on and secured to said seat, said neck portion having an exterior the lower edge of the cylindrical portion and into engagement with the wall of the body portion.
